I have an application where I need to make a Quartz movie using Quartz Composer and a custom plugin and have it run in a 3rd party application which is capable of playing Quartz movies.
As a first step I successfully developed my custom plug in using Xcode and 'built' a composition in Quartz Composer. I got this all running in Quartz Composer and this works totally fine in the viewer inside Quartz Composer. Subsequently I tried to play it in the 3rd party application and it would not play, other parts of the movie played but my plugin simply did not function. I then tried QuickTime player and on one machine it behaved exactly the same - movie played but my plugin didn't function. On another machine I get the error "Quicktime player quit unexpectedly while using the "My Plugin Name" plug-in. After this I was a little baffled and I read the forums and I came across the notion of Safe and Unsafe patches. I am wondering if this is why my patch doesn't work in applications other than Quartz composer. If I enable the "Indicate Unsafe Patches" menu item then it shows an unlocked padlock icon on plug in presumably indicating it is in fact Unsafe. Some questions: Am I on the right track, is it not playing my custom plugin because it is considered unsafe? How can I tell 'an application' or the system that it is safe? What is the correct way to achieve what I am wanting to do? Any other ideas, useful information welcome. I should also say I am mostly a Windows developer so I am new to Quartz technology and developing on a Mac. Thank you, Kind Regards, Callum.
